Arbitrum Launches Elara Update for Custom Chains

Arbitrum officially activated the ArbOS 61 Elara upgrade on August 20. This update introduces optional protocol level transaction screening specifically for dedicated chains. It gives developers more tools to manage how transactions are filtered and processed within their own networks.

Beyond screening, the update brings support for priority fees and a new data availability interface. These changes are designed to help developers build more efficient chains that better suit their specific operational needs. The upgrade also adjusted how base fees are managed to keep the network running smoothly.

Arbitrum One users will also see an increase in Stylus capacity. This expansion allows for more complex applications to run on the platform using familiar programming languages. Traders and developers should watch how these new compliance features affect institutional adoption for dedicated Arbitrum networks moving forward.
